Title: Arithmetic unit
Inventor: NAKAGAWA KATSUHIKO
IPC: G06F7/50
Filed: 1988-03-22
Abstract: PURPOSE:To test the operation of a carry anticipation circuit perfectly by providing a redundancy prohibiting means to validate only carry anticipation from each digit to the high-order digit of a digit based on an external command signal. CONSTITUTION:When a carry propagation control line 54 is set at 0, a carry propagation control transistor 41 is de-energized, and no carry from a carry line 51 to a carry line 50 is propagated. As a result, by taking either 16 kinds of combination of (0000)-(1111) by the output of 4 bits of a half adder 11 and activating the carry line 51, it follows that the carry line 50 is activated only when the output of the half adder 11 takes the combination of (1111). Thereby, it is possible to stop the redundancy of carry propagation by the carry propaga tion control transistor 41 generally, and the normal/defective condition of the carry anticipation circuits (56-53) can be affected on the computed result, and the test of the carry anticipation circuit based on the computed result can be performed perfectly.

Abstract: PURPOSE: To obtain a high-quality recomposed picture by controlling the voltage of the constant  current source of the A/D converter by the computer and then adjusting the counting sensitivity.   
     CONSTITUTION: Integrator 1 integrates the output signals of the detector which are delivered  according to the intensity and the duration time of the X-ray pulse generated in synchronization  with the X-ray pulse generating trigger signals based on the comparison level V 2  which is set to  comparator logic 2. Thus, the value is obtained in accordance with the intensity and the duration  time. When the integration is over, the discharge signals are delivered from logic 2 to turn on  FET switch 6. Then the reverse integration time during which the discharge signals are discharged in the form of the constant current from constant voltage source V 3  featuring the opposite polarity  to the output of the detector through resistance R for the integration and then returns to V 2  is  delivered in the form of the duration signals. The duration signals are then supplied to gate 4, and  the clocks generated from clock generator 3 are counted during that time through counter 5 to  obtain the digital output. In this case, constant current 7 featuring the varying voltage is controlled by control input 8 given from the computer to generate V 3  of each value, and then the output  count number counted, i.e., the counting sensitivity is adjusted.
